Title: Rolling bearing
Inventor: TANAKA HISASHI
IPC: F16C33/66
Filed: 2012-03-28
Abstract: PROBLEM TO BE SOLVED: To maintain lubricating performance over a long period of time while reducing torque, in a rolling bearing.SOLUTION: After assembling an outer ring 2, an inner ring 3, balls 4 and a retainer 5, a grease 7 is filled between the outer ring 2 and the inner ring 3. The grease 7 is filled in such a manner that it adheres to an axial direction outside in a raceway groove 8 of an inner circumferential surface of the outer ring 2 and forms a continuous annular form along a circumferential direction. Further, the grease 7 is filled with a space C between an inner circumference of the grease 7 and the inner ring 3 so that the inner circumference of the grease 7 annularly filled does not come in contact with an outer circumference of the inner ring 3. Because the grease 7 adheres to the inner circumferential surface of the outer ring 2 to be held separately from the raceway groove 8 of the outer ring 2 and the inner ring 3, it is not stirred by rotational movements of the outer ring 2 and the inner ring 3 while supplying an appropriate amount of lubricating agent, thereby allowing a torque to be reduced. Further, because a required amount of the grease 7 can be retained, excellent lubricating performance can be maintained over a long period of time.
